Zen Buddhism, a meditation-focused branch of Mahayana Buddhism, spread from China to Japan and Korea during the Tang Dynasty. Monks traveled between countries, bringing Chan teachings and texts that formed the basis for Zen and Seon schools in their respective lands.

In Japan, Zen developed into Rinzai and Sōtō schools, emphasizing different meditation practices. Korea saw the rise of Seon Buddhism with various mountain schools. Both countries integrated Zen principles into art, literature, and daily life, profoundly shaping their cultures.
